[flexcoders] update data through data service

Thu, 11 May 2006 05:28:42 -0700

I am using the following code to update the Arraycollection binding
with the Dataservice
And I get the error variable x is not defined
What I understand is the updated collection is not going to coldfusion
co.isUpdate() is returning false.
What am I missing?
Thanks


Flex code
===============

public function modifyItem(obj:ProductFileDetail,index:Number):void
            {
                  fileCollection.setItemAt(obj,index)      ;
            }

And my cfm code is
=======================
<cffunction name="sync" output="no" returnType="array" access="remote">
            <cfargument name="changes" type="array" required="yes">

            <!-- array for the returned changes -->
            <cfset var newchanges=ArrayNew(1)>

            <!-- Loop over the changes and apply them --->
            <cfloop from="1" to="#ArrayLen(changes)#" index="i" >
                  <cfset co = changes[i]>
                  <cfif co.isCreate()>
                        <cfset x = doCreate(co)>
                  <cfelseif co.isUpdate()>
                        <cfset x = doUpdate(co)>
                  </cfif>
                  <cfset ArrayAppend(newchanges, x)>
            </cfloop>

            <!-- Return the change objects, as this is how success or failure is
indicated --->
            <cfreturn newchanges>
      </cffunction>

The flex server dump displays the following after updating the
arraycollection content
